How I automated my EF Core boilerplate code (Visual Modeling)

Hey devs,

Like many of you, I’ve spent way too many hours writing manual OnModelCreating code and mapping entities. Recently, I’ve been looking for ways to speed up my data layer workflow, especially for projects with complex database relationships (like the POS/Integration systems I work on).

I decided to give Devart’s Entity Developer a try for a "Model-First" approach. The ability to design the ORM visually and just hit "Generate" to get production-ready EF Core code is a game changer.

I put together a 6-minute guide showing the full process from visual design to generated code:

For those who use visual tools: Do you find them better for maintainability, or do you still prefer pure Code-First? I’d love to hear your thoughts on this workflow.

(Disclaimer: I collaborated with Devart to showcase this, but the time-saving results are very real for my daily work).

5 Common Invoicing Mistakes That Cost You Time and Money

Introduction:

As a small business owner or a freelancer, you’re focused on providing the best service to your clients. But often, the invoicing process is complicated and drains a lot of your time and effort. Simple mistakes in creating and tracking invoices can cost you money and credibility. In this article, we’ll cover 5 common invoicing mistakes and how to avoid them to ensure you get paid faster.

Mistake #1: Relying on Manual Templates (Word/Excel)

The Problem: Word and Excel templates may seem easy at first, but they are inefficient. It’s too easy to make a calculation error, forget to update client information, or send the wrong invoice.
The Solution: Use a specialized invoicing system, like Invoicerapp. It performs calculations automatically, saves client data, and ensures every invoice meets the required standards.

Mistake #2: Not Tracking Late Invoices

The Problem: Do you remember every invoice that hasn’t been paid yet? Neglecting to track overdue invoices is one of the main reasons for losing money.
The Solution: Maintain a clear record of the status of each invoice (paid, overdue, or pending). Smart systems send you automatic notifications for late invoices, so you can follow up easily.

Mistake #3: Sending Unprofessional Invoices

The Problem: Your invoice is a reflection of your brand. A poorly designed invoice or one with typos can hurt your credibility and may make clients hesitant to pay.
The Solution: Use professional, ready-made templates. Make sure your invoice includes your logo, contact information, and clear details of your services or products.

Mistake #4: Non-compliance with Tax Requirements

The Problem: If you work in a country that requires VAT or other certifications, non-compliance can expose you to legal liability or fines.
The Solution: Choose an invoicing system that supports the tax and Zakat requirements in your region and generates accurate reports to avoid any future problems.

Mistake #5: Difficulty in Issuing Payment Receipts

The Problem: Even after receiving a payment, you might forget to issue a formal payment receipt. This affects your transparency with the client and makes it harder to track payments.
The Solution: Use a tool that allows you to issue a payment receipt with a single click as soon as you receive the money, and automatically link it to the original invoice.
Conclusion: The Solution Is at Your Fingertips

As a freelancer or a small business owner, your time is valuable. Avoiding these mistakes will help you save time, money, and effort. Don’t hesitate to use tools that simplify this process for you.
